INTERNALCOMBUSTION ENGINE.

Specification of Letters Patent.

Patented Sept. 5, 1911.

Application. filed January 13, 1909. Serial No. 472,007.

To all whom it may concern:

Be it known that I, ROBERT A. ltnrnonus. a citizen of the United States,residing at Detroit, county of Wayne, State of Michi an, have invented acertain new and useful mprovement; in Intcrnal-Combustion longines, anddeclare the following to be a full,

clear, and exact description of the smile, such as will enable othersskilled in the art to which it pertains to make and use the same,reference bein had to the acconin'mnying drawings, whic form. a part ofthis specification.

This invention relates to internal combustion engines.

It has for its object an improved engine having a reciprocating pistonand a rotating valve, with means for regulating the ignition apparatus,and means for regulating the flow of the fuel into the combustionchamber of the engine.

In the. drawings Figure 1, is an elevation, showing a side view of thevalve casing, and that portion of the cylinder which lies below thevalve case. Fig. 2, is a cross section at the line b-b, Fig. 1. Thisalso mrres onds to a cross section at the line b-b, ig. 3; Fig. 3, is asection taken along the axis of the cylinder, and along the axis Fig. 4,is a detail of a part of the connection between the throttle and thegovernor. Fig. 5, is a cross section through the valve and its casing,on the line aa of Fig. 2. Fig. 6, is a perspective of the valve removedfrom its case. Fig. 7, is a plan of the valve seat removed from thecase. Fig. 8, is a perspective of a throttle valve used in thevalve'seat. Fig. 9, is a perspective view of the valve, with the tlirottling and ignition regulating devices re moved.

lindicates the engine cylinder, in which. engages areciprocating piston2, which drives crankB and shaft 4. The fuel or explosive compound isadmitted into the cylinder 1 from its source of supply through an intakepassage 5 that leads into the valve casing (3, through a seat of thevalve, and through a port 7 in the valve disk 8. The valve disk 8 ismounted on a valve stem 9, which is driven in rotation by miter gear 10on thcstem, and gear 11 on the shaft For a four cycle engine the mitergears 11 and 10 bear the proportion of one and two. In the valve casing,directly underneath the val-vc disk 8, is a valve seat member 13,pierced with three ports, or three openings, the intake port 1W, theexhaust port 15 and the ignition port 13 The exhaust port 13 remains ofunvarying capactiy. The intake port 13' is provided with a throttle wing15,

and the ignition port 13 is provided with a wing 14, similar to thethrottling wing 15, which is used to advance or retardthe time ofignition of the charge. The rotating valve 8 rotates to coversuccessively enduncover successively the several openings or portsnamed, and when the openings 7 through the rotating valve 8 engages overthe opening 13, which is a continuation of the intake assage 5, theexplosive fuel passes into he valve chamber and thence into thecombustion chamber behind the piston 2. After the explosion, and afterthe iston has been driven to the full extent of its throw, the burnedproducts of combustion.

pass out through the )rimary exhaust 16, into the exhaust pipe ll, suchpart of them as remain in the combustion chamber. are lifted" and drivenout through the valve chambdr, and through the same passage 7, which nowregisters with the exhaust opening 1" "a At the proper time, in therotation of the valve, the opening 7 engages over the spark chamber 13in the seat, uncovers the ignition plug, whose ignition terminal islocated in this chamber 13, and the fuel is ignitedprimarily in thischamber, and the fire spreadsinto the cylinder 1. Betwcen'the throatopening 18 in the seat disk 13 and the stem 9 of the valve, is anannular chamber in which engages the ring terminal 20 of the throttlingvalve 14, or the ring terminal of the similar valve 14, which regulatesand times the ignition. On the under side of the wing valve 15 is acavity in which engages an eccentric cam 15, mounted on the end of anoscillatory shaft 28, which is oscillated by a link 23, and by cranklever 24; 'of these, the link 23 is actuated by a centrifugal governor25, of any approved character,

mounted to rotate with the valve stem- 9. The varying rotation of thegovernor shifts the valve 15, and varies the intake capacity of theport, regulating the size of the opening 26. The wing valve 15 rests onthe cross web of the valve casing which prevents the formation of apassage behind the wing valve. The valve 14 is regulated by a similarcam 14 actuated by'a stem 22,1and a hand lever 29, by means of which the'sten3 is turned and the ignition action advanced or retarded, as may bedesired. 'lhe'igni tion is preferably produced by a hot wire (heated byelectric current) in preferenceto the usual jump spark method. hecylinder is surrounded With an ordina Water jacket 28", and the upperopening into the valve casing is closed by a plug 29", through whichopening the valves themselves may be inserted; and. the necessarytooling for their accurate" seating may be effected.

The'ignition plug is inserted through the valve casing, and the ignitionterminal 27 thereof, leads into the opening 13*. As shown in Fig. 5, thewing valve is shown in position to entirely prevent the ignition.
